Abstract：Composite samples used in this study are fabricated by RTM and T700/6421 composite system. The samples were inspected by ultrasonic method. The effect of different laying-up direction on ultrasonic inspection was studied. And the results were given: the orientation of layers influences the velocity and attenuation of the sound wave in composite. So the compensation will be added when defect depth and material attenuation are measured. The orientation of layers of composite laminates doesn't affect the surface resolving power, the ability of finding the defect and the accuracy of estimating defect size.
